Fluoroalkyl silanes

Abstract

The present invention is directed to a fluorosilane represented by (L) 3 -Si—(CH 2 ) n —N(-Q 3 -R f )-Q 1 -R f where each n is independently an integer from 1 to 12; L is independently chosen from a hydrolysable or non-hydrolysable monovalent group R f is chosen from a C 2 -C 12 perfluoroalkyl provided that: i) one fluorine atom of the perfluoroalkyl can be optionally replaced by hydrogen, and/or ii) the perfluoroalkyl can be optionally interrupted by at least one oxygen, methylene, or ethylene; Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene optionally interrupted by at least one divalent organic group; X 1 is chosen from O or S; and b) Q 1 and Q 3 are independently chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one of —C(O)—O— or —O—C(O)—, and optionally further interrupted by at least one divalent organic group.
